To all whom it may concern:

Be it known that I, ,CHARLEs I. DEANE, a citizen of the United States,residing at W'alla WValla, in the county of Walla Walla and State ofWashington, have invented certain new and useful Improvements in; Piles,of which-the following is a specifi,

cation.

This invention relates to piles which are formed of reinforced concrete,and its object is to provide a pile which can be easily and cheaplyconstructed, and which is strong and durable.

In order that the invention maybe better understood, reference is had tothe accompanying drawings, in which Figure 1 is a plan. view of a pieror dock, partly broken away, showing the method of using the piles. Fig.2 is a side elevation of the pier or dock, partly broken away. Fig. 3 isan elevation-of one of the piles. Fig. 4 is a top plan view thereof.Fig. 5 is an elevation of the pile, partly in section. Fig. 6 is alongitudinal section of the metal reinforcing core of the pile. Fig. 7is a sectional view of a modified form of driving shoe.

Referring specifically to the drawings, my improved pile comprises acentral steel or other metallic core 10 in the form of a tapered tube ofsuitable length according to the desired length of the'pile, and a shell11 of concrete in which said core is embedded. The pile tapers in thedirection of its lower end as usual. If desired, the concrete shell mayhave a suitable reinforcing element 12.

The pile has a head 13 comprising a steel ring which is riveted orotherwise rigidly fastened to the upper end of the core 10 and encirclesthe same. The head has a bottom recess 14 formed by providing the ringwith an annular flange 15 surrounding the same in spaced relation and.concentrically.

The bottom of the pile is armed with a steel driving shoe 16 whichlatter is solid and substantially conical. The shoe has a top recess 17at the center of which is an upstanding threaded stud 18 which isscrewed into the lower end of the core 10,

The recess 17 tapers inwardly and the lower. end of the core seatssquarely on the floor.

that a portion of the recess left open to receive the concrete materialat ,the bottom o the pil In h s m manner, th material at the ,top of thepile upthe recess 14. Thus, a support for the concrete at the end o thep i lead, and-th s el o th material surrounding the core 10 'is' rmlyheld and braced. The shell is flush with the outer surface of the shoe16.

At 18' are shown eye-bolts which may be screwed into the core 10, andthey project from the surface of the pile a sufiicient distance topermit the attachment of stays 19 and lateral bracing rods 20 as shownin Figs. 1 and 2.

The pile will be made complete, ready for driving, and it may be drivenin the usual manner, as any ordinary pile. If the jet system is used,the shoe 16 will have a vertical aperture 21 extending entirely throughthe same, as shown in Fig. 7 to afford an outletat the point of theshoe. If the pile is not to be jetted, the core 10 need not be tubular,but may be solid. If a tubular core is. employed, the same may be filledwith concrete, after the pile has been driven, leaving enough of thecore unfilled at the top to permit the insertion of a post 22 for theattachment of the connections 23 shown in Figs. 1 and 2. This post is ofsuch size that a railing post may be secured to it if required.

Figs. 1 and 2 show how the pile may be employed in a pier'or dockstructure, and the system of stays and bracing employed.

The pile herein described is adapted for' foundations, piers, docks, orany other construction requiring a system of piles, and by its use thecost of the construction is lowered without lessening the efliciency ofany of its parts.

I claim:

1. A pile comprising a metallic core, a head permanently fastened to theupper end of the core, a driving shoe permanently fastened to the lowerend of the core, and a concrete shell rigidly attached to and sur-.rounding the core between the head and the shoe the head covering theupper end of the concrete shell, said core, and its head and shoe beingpermanently incorporated in and forming a part of the pile and the meanswhereby the pile is driven.

2. A pile comprising a metallic core, a. ring fastened to and encirclingthe, core at the top thereof and having a flange surrounding the ring inspaced relation, and a concrete shell rigidly attached to andsurrounding the core and filling at its upper end the spacebetween theaforesaid ring and its flange, said core being permanently inporporatedin and forming a part of the pi e.

3. A pile comprising a metallic core, a

ring fastened to and encircling the core at the top thereof, and havinga flange surrounding the ring in spaced relation, a driving shoefastened to the lower end of the core. and a concrete shell rigidlyattachedi CHARLES I. DEANE.
